    Moisture will get though anything, don't worry about it.

    When we used to fit PV back in 2012, we had to install on dozens of old slate roofs (they are pretty common down here). Nearly all got damaged and most had to be reinforced. As I was the 'engineer' for the company, I suggested to the sales team that they either said no, or doubled the price. Thankfully the company went bust, so they only ruined about 30 houses.

    I suspect it is easier to deal with one company that manages a few thousand houses, than a few thousand customers that have 1 house each. The glycol saving is probably a real saving if it is changed on a regular basis, as it should be.

    Had a quick skim though, seems like a reasonable idea. Not idea how it will affect overall SCoP.

    Is that Scottish-Japanese company still going. Akai

    Good on you. As you have vaulted ceilings, is there going to be above building reg insulation. I understand why you want pocket doors, will make you life easier. They do tend to be noisy, but I would think that there are quieter ones, just a case of putting in rubber wheels, rather than nylon ones.

    I would think it would dry out naturally. If there was 100g of water per m2, which is quite a lot, then it will take 226 kJ/kg of energy to vaporise it. That is 0.063 kWh. So not much in the scheme of things really. (As with all things science, it is not as simple as that, but a good enough first approximation)

    Hard to believe, considering he is from Pisstool.

    That is a lot of trips to the picture house.

    Seems icon, instead of the image, have been uploaded. You can usually copy and paste an image into a post, some formats are not supported though. Pasting in file paths does not work, which is what seems to have happened here.

    TL:DR You ideally needs to split your PV across the phases you use during the daylight hours. Net Metering may be possible with your energy company, but check first, and check if you can get a Net Meter fitted. And, kW is power, kWh is energy.

    Sounds like Sierra Leone when it comes to deforestation.

    How about cross laminated timber (CLS). Typical k-value of 0.13 W.m-1.K-1.

    May be worth looking to see how much PIR sheets cost. Applied externally, and then covered in a weatherproof membrane or coating should help a lot. You may find that the costs are not that high, Europe is a high mark up country after all.

    PV and Air to Air Heat Pumps then. Heating and cooling taken care of. Not been to Chile, only Venezuela and Columbia, I lived just of the coast of Venezuela when I was a teenager.

    Probably made with a fire retardant resin. MDF is really hard to set alight, as are some ply woods. Depends on the binder/adhesive used.

    Not sure how it works. Grid supplied electric will have a CO2 intensity. Domestic PV will also have one, but no idea what the current figures are.

    The Nobel Poet? I would have thought that Chile, with it's advanced mining industry would have a strong industrial base that manufactured most products. Solar gain can be counteracted with reflective surfaces cheaply.

    At first reading/quick glance, it seems sensible. Does have a lot of drawbacks compared to mineral wool (internally) or ESP/EPX/PU boards (externally). I am not sure how the embodied energy (EE) figures compare to other materials. I had one of these to keep me warm when I was a teenager. Though others like this.

    In my experience, whenever a government tries to make things simpler, all that happens is that a new, overcomplicated, system is created. Think MCS microgeneration. I did hear on the wireless this morning, that heat pumps can be fitted within a metre of a neighbouring boundary (without planning permission), will we interesting to see if the noise limits get changed.

    I suspect there is a problem with water absorbtion, this would not only increase the thermal conductivity, but would weight more. Expanded perlite can have a density of between 32 and 400 kg/m³. If something is not in common usage, there is generally a good reason for that. Does ChatGPT have anything to say about the energy needed to process it into expanded form?
  23. SteamyTea
    Très bien
  24. SteamyTea
    Was it a system installed under the MCS? If so, you may be able to get so redress.

    Add some garlic, sauté lightly and you can eat the snails as well, Monsieur. If you have parts that do not get much traffic, you can carpet them to stop growth. (Is that sounding rude, waiting for a rug or welcome mat comment)
